Reading and writing Microsoft Works documents(OpenOffice cannot do that)

Can save your documents as PDF.

Easy to use - includes a lot of documention in both english and danish.

LibreOffice.org is a complete office suite, a variant to OpenOffice.org, much like Microsoft Office in funktionality, and besides being able to read and create files in Word, Excel and other Microsoft Office formats, it can also create a PDF version of your document, which can be read by anyone with a PDF reader, so the recipient of the document does not need to have LibreOffice installed to read your document. This is something Microsoft Office doesn't offer.
